Snow blindness is an inflammation of the cornea and conjunctival epithelium due to damage caused by ultraviolet light. Snow blindness is the refraction of ultraviolet rays from the sun onto snow, causing the eyes to react in different ways, such as tearing, redness of the eyes, and difficulty in seeing the outside world. It manifests as redness and swelling of the eyelids, congestion and edema of the conjunctiva, severe foreign body sensation and pain, photophobia, tearing, and blurred vision during the onset of the disease. Snow blindness is caused by ultraviolet light reflected from snow that damages the cornea, conjunctiva or retina of the eye, causing a series of symptoms of eye discomfort. For localized corneal epithelial damage caused by snow blindness, recombinant bovine basic fibroblast growth factor drops are recommended to restore corneal epithelial growth. If antibiotic drops are available, levofloxacin drops can be used for anti-infective treatment. In addition, after the diagnosis of snow blindness, some people will experience relief from the above treatments. If they are not effectively relieved, they need to go to the hospital to check the specific cause of the disease and treat the symptoms.
